How to Read an Options Chain: Step-by-Step Guide for Beginners

The options chain is the first thing that breaks most new traders.

You open your broker, find a stock or ETF you want to trade, click on ‘options’ — and suddenly you’re staring at a wall of numbers, columns, and expiration dates that make no sense. Most people close the tab and go back to stocks. The ones who figure out how to read it properly gain a real edge.

This guide is the breakdown you actually needed before your first options trade. Every column, every term, in plain English — no finance degree required.

By the end of this, you’ll know what every major column means, how to filter for the right options, and the mistakes most beginners make when they try to read a chain for the first time.

What Is an Options Chain?

An options chain is a table that lists all available options contracts for a given underlying security — a stock, ETF, or index — organized by expiration date and strike price.

Think of it as a menu. The underlying (say, SPY) is the item. The options chain shows you every way you can structure a position on that item — different strike prices, different expiration dates, calls vs puts, and the associated pricing and activity data for each.

Every options chain has two sides:

• Calls — the right to buy the underlying at a specific price
• Puts — the right to sell the underlying at a specific price

Most brokers display calls on the left, puts on the right, with the strike price column in the middle. Expirations are usually selectable at the top or arranged in tabs.

Step-by-Step: Every Column in the Options Chain Explained

Step 1 — Choose Your Expiration Date

Before you look at anything else, you choose an expiration. Options expire on a specific date, and all the data you see in the chain applies to that expiration.

Major ETFs like SPY and QQQ now offer daily expirations (0DTE — zero days to expiration), weekly expirations, and monthly expirations. For beginners, starting with weekly expirations (7-14 days out) provides more time for the trade to develop while keeping premiums reasonable.

Key point: The closer to expiration, the faster the option loses time value. More on this when we cover theta.

Step 2 — Read the Strike Price Column

The strike price is the price at which you have the right to buy (call) or sell (put) the underlying.

If SPY is trading at $530, and you buy a $535 call, you’re buying the right to purchase SPY at $535 — above the current price. For that call to be ‘in the money’ at expiration, SPY would need to be above $535.

Options are categorized by where the strike sits relative to the current price:

• In-the-Money (ITM): The strike has intrinsic value. For a call, this means the strike is below the current price. For a put, above.
• At-the-Money (ATM): The strike is at or very close to the current price.
• Out-of-the-Money (OTM): The strike has no intrinsic value yet. For a call, the strike is above the current price. For a put, below.

Most platforms highlight or shade the ATM strike to help you orient yourself.

Step 3 — Bid and Ask Price

These two columns tell you the current market price for the option.

• Bid — what buyers are willing to pay for the option
• Ask — what sellers are willing to accept

You buy at the ask and sell at the bid. The difference between them is the bid-ask spread, which represents an immediate cost the moment you enter.

A spread of $0.01-$0.05 on a liquid ETF like SPY is normal and acceptable. A spread of $0.50+ on an illiquid contract is a warning sign — it means you’re paying a significant premium just to enter, and you’ll need a bigger move to overcome that cost.

Always check the spread before entering. Wide spreads eat into your edge before the trade even starts.

Step 4 — Last Price

The Last column shows the most recent transaction price for that contract. On actively traded options, this updates frequently. On illiquid options, the last trade might have occurred hours ago — which is why bid and ask are more reliable for pricing.

Don’t use the last price alone to evaluate an option. Use it as context alongside the bid-ask.

Step 5 — Volume

Volume shows the number of contracts traded today for that specific option.

High volume on a particular strike or expiration tells you that other traders are actively interested in that contract. It’s a rough proxy for liquidity — more volume generally means tighter spreads and easier fills.

Volume resets to zero each morning at the open.

Step 6 — Open Interest (OI)

Open Interest is the total number of outstanding contracts that have not been closed, exercised, or expired. It accumulates over time, unlike volume which resets daily.

High open interest at a specific strike often acts as a magnet or a wall — large concentrations of OI at particular levels can influence how the underlying moves around those prices. Traders and market makers with positions at those strikes have an interest in price staying near or moving through those levels.

For beginners, focus on open interest to find liquid strikes and identify which levels the market ‘cares about.’

Step 7 — Implied Volatility (IV)

Implied Volatility is the market’s forward-looking expectation of how much the underlying will move over the life of the option. It’s expressed as an annualized percentage.

Higher IV = more expensive options. Lower IV = cheaper options.

IV rises when there’s uncertainty (earnings announcements, Fed decisions, major news events) and falls when the market calms down after an event. ‘IV crush’ refers to what happens when IV drops sharply after an anticipated event — even if the underlying moves in your direction, your option can lose value because the uncertainty premium deflates.

As a beginner, pay attention to whether IV is elevated before you buy options. Buying options with high IV means paying a premium that can erode quickly.

Step 8 — Delta

Delta measures how much an option’s price is expected to change for every $1 move in the underlying.

• A call with a delta of 0.50 will increase in value by approximately $0.50 for every $1 SPY moves up
• A put with a delta of -0.40 will increase in value by $0.40 for every $1 SPY moves down

Delta ranges from 0 to 1.00 for calls and 0 to -1.00 for puts. ATM options have a delta around 0.50. Deep ITM options approach 1.00. Deep OTM options approach 0.

Delta is also used as a probability proxy — a 0.30 delta call is roughly considered to have a 30% probability of expiring in the money.

Step 9 — Theta

Theta measures time decay — how much value an option loses each day due to the passage of time, all else equal.

Theta is always negative for option buyers. Every day that passes, your option loses a small amount of value simply because there’s less time for the trade to work. This effect accelerates as expiration approaches.

If you’re buying options, theta works against you. For longer-dated positions, theta decay is manageable. For short-dated or same-day options, it’s aggressive and relentless.

How to Filter for the Right Options

Reading the chain is step one. Selecting the right contract is where the skill kicks in.

Liquidity First

Before anything else, confirm liquidity: volume above a few hundred contracts, open interest in the thousands, and a tight bid-ask spread. If any of those aren’t present, skip the contract regardless of how good the setup looks.

Strike Selection Based on Your Thesis

Your strike should align with your trade thesis. If you’re expecting a moderate move higher in SPY, buying an ATM call gives you the most directional sensitivity. If you want lower cost with higher leverage, a slightly OTM call reduces premium but requires a bigger move to profit. If you want to reduce risk with a more conservative position, a slightly ITM call gives you more delta and less time decay sensitivity.

There’s no universally ‘correct’ strike. The right strike depends on your entry thesis, your expected move, and your defined risk.

IV Awareness

Before buying, check if IV is elevated. If you’re looking at an option on an earnings day, IV could be 2-3x higher than normal — meaning you’re paying significantly more for the same contract. Sometimes that’s justified. Often, it’s a trap.

Experienced traders track IV rank (where current IV sits relative to its historical range) to contextualize whether options are cheap or expensive relative to their own history.

Common Beginner Mistakes When Reading the Options Chain

Only looking at the last price — The last price may be outdated. Use bid and ask for real-time pricing.

Ignoring the spread — A $0.40 wide spread on a $1.20 option means you’re immediately down 33% on the trade. Liquidity matters.

Buying deep OTM options for low cost — A $0.10 option looks cheap until you realize it needs a massive move to have any value. Cheap premium doesn’t mean good value.

Not checking IV before buying — Buying during high IV periods means overpaying. Options can move against you even when the underlying moves in your favor if IV collapses.

Ignoring open interest — Low OI on a contract makes it hard to exit cleanly. Always check that you can actually get out of the position if needed.
